Question

find the length of the unknown side in the following right angle triangle

Answer 1

HEYA MATE, HERE IS UR ANSWER


$<b><i>Hypotenuse =15 cm$

Base=12 cm

We can apply Pythagoras Theorem here

Hypotenuse^2=base^2+perpendicular^2

15^2=12^2+perpendicular^2

225=144+perpendicular^2

225-144= perpendicular^2

81= perpendicular^2

9^2= perpendicular^2

9= perpendicular =x

$\huge\boxed{\mathbb{BE\:BRAINLY}}$

Answer 2

according to pythagoras theorem,

15^2= x^2 + 12^2

x^2=15^2- 12^2

x^2=81

take square root on both sides,

x=9
